v THE CHURCH OF S. ANDREW IN KRISEI 117
It should be particularly noticed that the windows over the western dome arcade are circular-headed inside3 though they have been provided with pointed heads on the outside in the process of refkcing.
If we stand in the northern lateral apse and face the mihrab the reason for the alterations is evident. The original Christian orientation is ignored, and the apses? in place of being latera!3 are terminal. To the left is the old apse left unaltered ; to the rlght? the original filling of the dome arch forms a c nave-arcade' similar to that of the mosque of Sultan Bayazid ; while by means of the additional apses the building has been converted into a miniature imperial mosque of the S. Sophia type, a distinctly clever piece of Turkish alteration.
In its original form the central dome was surrounded by an c ambulatory' of one. story formed by the aisles and * inner narthex.' Such a plan is common to both the domed basilica type and the domed cross type? the difference depending upon the treatment of the cross arms above. In both types, however, the side dome arches are invariably filled in with arcades similar to that filling in the western arch of S. Andrew. We are therefore justified in restoring such arcades here. The type thus restored differs from the domed cross church in that the cross arms do not extend to the outer walls3 and from the domed basilica in that the western dome arch is treated - in a similar manner to the lateral arches. To this type the term c ambulatory church ' may be applied.
Adjoining the west end of the church is the fine cloister of the Tek6 of dervishes, probably on the lines of the old monastery. All the columns around the court are Byzantine, and one of them bears the inscription : the (column) of, Theophane—rj T% ®e&><t>dvys (Fig. 69). In the south wall is built a beautiful Byzantine doorway having jambs and lintel decorated on the face with a broad undercut scroll of flat leaves and four-petalled flowers^ running between two rows of egg and dart, while on the intrados are two bands of floral ornaments separated by a bead moulding. One .of the bands is clearly a vine scroll The method employed here,
